Dan Carlin did a very timely 5 hour podcast on the dropping of the first atomic bomb on Japan, and the following years’ debates among the politicians (scientists were mostly excluded from the debates).
This is history worth knowing, but it’s especially pertinant to this post truth age of Trump. One thing described and emphasized in this podcast is that the President of the United States is the ONLY decider on whether to use nuclear weapons.
Because this (and all his) podcasts are several hours long, you will want to subscribe to him and download it (and other episodes) on your device for convenience.
